Lolig's manga / #Ex Host(2)

Kyouya has abandoned his infatuation for Homura, the yakuza boss of the host club where he once worked, and has now fixed his sights on Kiriya, the emotionally distant assistant professor of cultural studies at the university Kyouya now attends. At first, the pair antagonize each other, and some of the blows they come to (both emotionally and physically) are a bit over-reactive, but Kyouya's openness and "glue-like" perseverance have ways of warming the hardest hearts.

From Exiled Rebels Scans:Tachibana Yuuichi, who lost both of his parents and sister in a traffic accident, took in his seven year old nephew, Ayumu. To create a new life, he moves them to the city where the sea can be seen, so they can focus only on themselves. They meet Kurebayashi Ryou who runs the local souzaiya. Even though he is the same age as Yuuichi, he is a popular person who has his own shop and is loved by the neighborhood. Taking things day by day, will these three be able to overcome the lingering fears from their pasts?
